16 New Plants. [ ZOE 
inches long, purplish, capillary bent at right angles above the mid- 
dle; scales of the involucre separate nearly to the base, lanceolate 
or ovate-lanceolate, obtuse, 1 line long, hyaline margined, erect; 
flowers 5 to 10 on pedicels % a line long, ovate with a contracted 
base and the lobes connivent at tip, 1 line long, pubescent with very 
stiff short hairs, but scarcely glandular, sepals 1 line long and very 
narrowly triangular, three times as long as wide, golden yellow, the 
pubescence confined to the lower half, midrib prominent. The 
nearest congener is £4. salsuginosum. The tlowers are much the 
same, but the akene of flexum is brown, broadly ovate, very nar- 
rowly winged at the abruptly contracted summit, not at all winged 
in the middle, and slightly so at the base. The akene of &. sa/sug- 
inosum is simply ovate, and winged throughout and conspicuously 
so at the base and broad apex, and is yellowish brown, they are the 
same size. &. flexum resembles £. trichopodum in habit. £. sal- 
suginosum is a small, erect, closely branched annual, with some of 
the upper involucres long peduncled, and the rest sessile, 
Collected June 10, 1890, on the Moencoppa in northern Arizona. 
It grows on dry mud flats. 
There are two plants which need characterizing, one of which has 
been known for ten years—two species of Stanleya. The first is a 
very conspicuous plant from the wide sandy valleys of western 
evada. 
STANLEYA ELATA. 2 to 6 feet high, erect, short lived or bien- 
nial, branching toward the top, glabrous to the flowers, and often 
glaucous; leaves very thick and leathery, veiny, generally entire, 
but sometimes with a few small lobes at the base, 4 to 10 inches 
long, obtuse, oval or ovate generally cuneate at base and contracted 
into the margined petiole which is seldom over 2 inches. long; upper 
leaves lanceolate, acute, on a half-inch petiole, entire and contracted 
at the base, lower leaves slightly and irregularly dentate, spikes 
simple or compound 1 to 2 feet long and very showy from the 
golden glabrous sepals which are half an inch long and enlarged 
into a blade 2 lines wide; petals about 4 lines long, light yellow and 
inconspicuous, claw broadening to the base and glabrous, blade 2 
lines long and scarcely wider than the upper part of the claw, nar- 
rowly linear; stamens twice as long as the petals, anthers loosely 
‘coiled, filaments glabrous down to the middle then very woolly to 
the base, with short, broad and flat hairs, not enlarging much at base;
